Potentially inappropriate prescribing in hospitalised children: a retrospective, cross-sectional study at a tertiary children's hospital in China.

Medications for long-term hospitalised young children with multiple comorbidities should be minimised and optimised, to avoid PIP, reduce adverse drug reactions and ensure children's medication safety. The surgery department and PICU had a high prevalence of PIP in the studied hospital and should be the focus of supervision and management in routine prescription review.
